From the obtained polarizing micrograph Figure 2 (a), since the texture similar to the oily streak texture expressed in chiral nematic liquid crystal phase was confirmed, was presumed that the liquid crystal phase S-CBCl a chiral nematic liquid crystal phase . Was also inferred in part of Figure 2 (b) since it was confirmed a texture similar to a fingerprint-like organization and do not chiral nematic liquid crystal phase. However, we believe that the helical pitch there is a short possibility, Grandjean future - and hopes to do the measurement of the helical pitch length using Canot method.
Since both ends of the S-CBI4 is flexible chains, more difficult to take the packing, and that the crystallinity is deteriorated, the melting point of the S-CBI4 was thought that than decreased from S-CBCl. However, towards the gold complex with chloro as a ligand has good stability, it was found to have a wide liquid crystal temperature range. In addition, the gold complex having a chloro a ligand that has been introduced citronellol flexible strand than the melting point drops, the system also infer a double bond and the branching structure contributes to reduction in the melting point.
